System and device for nearfield gunshot and explosion detection

Patent# US 10,054,576 B2

AbstractA computer - implemented system for nearfield gunshot and explosion detection comprising a hardware device with a differential air pressure sensor , a pressure amplifier that amplifies pressure signals generated by the differential air pressure sensor , a microphone , a microphone amplifier that amplifies audio signals generated by the microphone , and a pulse counter that calculates a total event length . The system includes a digital processor that processes the amplified signals from the differential air pressure sensor and the microphone and a data radio that generates alerts based on input from the differential air pressure sensor and the microphone . The system determines whether a gunshot event or an explosive event has occurred based on a pressure length sensitivity setting , a microphone length sensitivity setting , and a correlation sensitivity setting.
